Abstract

The purpose of this research was to describe the effectiveness of a problem solving learning model on electrolyte and non electrolyte solution material. The method used was a quasi-experiment with the matching only pretest-posttest control group design. The population on this research was all of the students from Senior High School Al-Azhar 3 Bandar Lampung in grade X IPA. The research sample was determined by purposive sampling technique, in order to obtain class X IPA 4 as the experimental class and X IPA 3 as the control class. The data analysis technique used is the difference test of two means using the t-test. The results showed that the n-gain mean of science process skills in the experimental class (0.67) was in the medium category; There is a significant difference in the average posttest score of science process skills between the experimental class and the control class. Thus, it can be concluded that the problem solving learning model on electrolyte and non-electrolyte solution material is effective for increasing students' science process skills. Keywords: electrolyte and non-electrolyte solutions, science process skills, problem solving learning models.

Abstract:Problem Solving Model to Improve Problem Solving Skills in Electrolyte and Non Electrolyte Solution. This study aims to describe the effectiveness of problem solving learning models in electrolyte and non-electrolyte solution materials to improve problem solving skills. The research method used was a quasi-experimental method with the matching only pretest-posttest control group design. The population of this study were all students of class X IPA SMA AL-Azhar 3 Bandarlampung in the 2019/2020 academic year. The research sample was determined by purposive sampling technique, so that the students of class X IPA 4 as the experimental class and class X IPA 3 students as the control class were determined. The data analysis technique used is the difference test of the two means. The results showed the n-gain of problem solving skills in the experimental class was 0.57 which was categorized as moderate; There is a significant difference in the average post-test score between the experimental class and the control class. Based on these results, it can be concluded that the problem solving learning model in electrolyte and non-electrolyte solution material is effective for improving problem solving skills.Keywords: Model, Problem Solving Problem Solving Skills, Electrolyte and Solutions Non-Electrolyte
